IMPROVEMENT IN EEDUGING MANGANESE ORES.

Be it known that I, CHARLES ADAMS, of Philadelphia, county `ol' Philadelphia, State of Pennsylvania, have invented an Improvement in Reducing Manganese; and I do hereby declare the following `to be a full, clear, and exact description of the same. v

My invention consists in reducing ores of manganese by carburetted hydrogen gas under pressure, as described hereafter.

In order to enable others familiar with processes of this class to practise my invention, I will now proceed i to describe the mode of carrying the same into ell'ect, reference being had to the accompanying drawing, 'which forms a part of this specification, and in which- Figure 1 is a sectional elevation of apparatus which may be used in carrying out my invention', and Figure 2 asectional plan on the line l 2, fig. 1. A A are 'the side walls of a furnace, in which is secured a. metal retort, B. and below one end of the latter is a grate, X. Near tbe centre of the retort is a safety-valve, D, with which communicates a tube, b, thelower end of the latter projecting into a closed vessel, E,'which is partly filled with water, and tothe front end of the retort is fitted a cap or cover, a. A- ppe, c, extends from the top of the vessel E throughA the wall A, and into the fireplace l'above the fuel, for a purpose described` hereafter. Manganese ore is introduced into the retort, together Ywith tar, petroleum, or other hydrocarbon, the lid a is secured firmly-in its place, and a fire is kindled in thefurnace. After the manganesein the retort has been heated to such a degree as to liberate 'a portion of its oxygen, the safety-valve is raised, when the gas will pass from the retort through the tubes b and c into the replace, where it will aid in consuming the products of combustion, the water in ,the vessel E acting as a trap to prevent the ame (should an ignitiblegas be liberated) from passing to the retort. After the-escape of` the gas, the valve is again closed until the material in the retort is at such a temperature, and the gases attain such a pressure, that a combination is effected between the remaining portion of oilygen in the manganese and the carburetted hydrogen gas evolved from the tar or other material. fBy the extraction of the oxygen from the manganese ore, as' thus described, atcrude manganese or carburet of manganese' is formed, which is highly valuable for combining with iron in the'nanufacture of steel, and for other purposes.

Although' I have shown and described a particular form of apparatus for reducing the manganese with car-` buretted hydrogen gas under pressure, it will be apparent that the character ofthe apparatus may be varied without departing from the main V4feature of my' invention..

I claim as my invention, ariddesire to secure by 'Letters Patent- The reduction of the ores of manganese by carburetted hydrogen gas under pressure, in the manner described. In testimony whereof I have signed my name to this specification in the presence of 4two subscribing witnesses.

CHARLES ADAMS.
